The funetion of this pipe is to equalize the pressure between the tank and the generator and to prevent the gasolene in the generator from rising higher than that in the-tank, thus insurin: the safety of the apparatus in this rticular by preventing the escape of gaso ene at all times, whether it is caused by a leak in the burner or the needle-valve being opened. Should the subtlame from any cause go out when the other burners are in use, the generation of vapor will be stopped and the air from the aetomet'er will pass through pipe K and escape through,needle-.openings, allowin the aerom'eter-to rapidly descend. When it s down all the way, all pressure is removed and all escape of vapor ceases.

In order that eommingled airand vapor -should besupplied to the pipe I as fast as the latter conveys it to'the subtlame-chamber, as hereinafter mentioned, the tank A'must be supplied with air under pressure. The ipe L, communicating with thevapor-an -air space in the tank, supplies the requisite air under pressure.

Another function of the aerometer is to keep the vapor in generator 0 under-pressure after the generator is heated and when in use,

- water-tank M, slides up and down with the latand is used in lieu of an elevated tank such as is commonly used on gasolene stoves, which .is for the purpose of causing the vapor to leave the needleopenings wi.h force, and thereby cause it to entrain air as it enters the comnnngling tube. A. suitable device for supplying such air under pressure to the pipe of said water-tank or in a line near to said.

axial linc.. It terminates at the top in a valve-chamber M, inclosi'ng a check-valve M, which latter allows the air to enter the tube L at this end, but prevents its sudden egress therefrom. A movable vessel N, preferably cylindrical and nearly as large as the season ter. This vessel will be termed the asrome ter N. It is closed at the top and open at the bottom. The valve M M is always within it even when said cylinder is. the most .highly elevated. In the top or upper portion of the aerometer N is a check-'valveN, preferably a flap-valve, allowing air to enter the aerometer as the latter is elevated, but pre- The aerometer is of such a length as that "when it is down at the bottom of its moveface of the water at the tank M and that when raised to its highest point its lower end will still be in the water of the tank. The aerometer carries at its side and near the top tensinks to strikeapin J of the arm Peterssaid and carry down the latter, thereby-closing the valve, and thereby closing the pipe I. The aerometer is providedabove with a suitable device N, whereb it may be lifted by hand or by a rope attac ed thereto and run over a pulley.

The construction of my invention having its mode of operation is as follows: The tank A is filled with gasolene, but not so high as the needle-openings nor so high as to close oi! the air-space in the tank, into which pipes K, I, and L enter, so as to prevent the air from filling the tank A the stand or generator C is tilled, as shown. The tank M is part y filled with water, asindicated. The aerometer N is elevated, as in Fig. 2, and the valve J opened, as shown in that figure. The aerometer, being allowed to descend, presses the air within it into the va r-space of tank A and on through the wiekmg 1', through valve J and pipe I to the subiiame-chamber. The air thus carried forward is permeated. and mixed with the vapor of the hydrocarbon. As this mixture issues from the opening H of the subflame-chamber it is lighted and begins to heat the enerator-pi C and the metal of the n le-valve ho ders, .needle valves, and chamber D. Any vapor thus generated inpipe 0 passes up into chaniberD and through pipe K into tank A and is there condensed until needle-valves E are opened, when part or all of the vaporpasses through uesthus to furnish fuel. The needle-valve E of the commingling-tube F, which is to supply commingled airand vaporto thesubflainechamber, is opened. When the aerometer has nearly reached the lowest point of its movement-,-it has, through the agency of the tappet N, depressedthe arm and closed the valve J. Further supply of air and vapor through the pipeI is thus stopped, thereby stopping the rapid descent of the aerometer; but by thistime, owing to the predetermined arrangement of the capacity of the aerometer in proper relation to the amount of commingle'd air and vapor furnished through pipe I venting its egress as the aerometer descends.

and,n eede'dtor the heating of the generator to a degree sufiicient to generate vaporfrom the gasolene within it, such vapor is already being generated by the generator and is passiug through needle-valve E, as shown in Fig. 3,.and into thecommingliug-tube F and there, mixed with air, furnishesa fuel for the flame,

,, whereby the operation of'keeping the gener-.

ator G snfliciently heated to generate vapor for quite a while before the aerometer will go down is carried on." The aerometeris pref-' 'erably at all times up while the burner is in use-that is tosay, above the point wherein '-Z descending it would rest. Beingin this po- 5. .7 preaure on the gasolene in the tanlrandgensition, the aeromet-er produces the necessary erator by which aconstanto'r steady and nonilickering flame is maintained at the burners.

It will be un- -derstood that the other needle-valves, in conjunction with; their tubes F, supply fuel to the burners of stoves and otherarticles in any of the modes well known orthat may be desired'.,
